Now for a program to turn iPhone apps into web pages. Immediate download! No app store! No space tied up on your phone! Searchable with Google!

Slowed rendering! Lower responsiveness! Non-native controls widgets! No good way to monetize them! Not able to take advantage of all native APIs! Can't use offline except with the limited storage APIs! Worse battery performance for demanding code!

...For now. You should have a play with a Chromebook, Web software is incredible when the hardware / APIs are there :)
